Flashcards in cardiology/renal/repro 1-27 54% Deck (28):
relation of aorta and IVC
right side-IVC and left side-aorta
75 year old pt with a fib and past history of thromboembolic dz, give warfarin and not heparin because
heparin is used to for antiplatelet therapy in pts under 75 w/o past history of thromboembolic dz and low risk of a fib. give warfarin for higher risk pts
drug that can replace captopril if pt has cough is losartan and not exenatide or sitagliptin because
captopril and ACE I can be replaced with and ARBs losartan
exenatide-is glucagon like peptide (GLP-1) used to treat DM2.
sitagliptin is dipeptidyl peptidase-4 inhibitor (DPP-4) used to treat DM2
what is used to measure cardiac function after MI:
- troponin T or troponin I
-CK-MB or total creatine kinase
primary force of coronary artery flow?
aortic pressure not ventricular contraction
removal or kidney or any organ causes CO and TPR and total renal blood flow and BP to
CO decreases, TPR increases, total renal flow decreases, BP remains constant b/c organs are arranged in parallel.
1/total resistance=1/R1 +1/R2 + 1/R3
pt with red, swollen, tender breast with firm mass has dermal lympathic invasion by cancer cells and not epidermal invasion or fat necrosis because
pt has inflammatory breast cancer-cancer cells invade dermal lymphatics and cause pea d-orange
epidermal invasion by cancer cells-Paget's disaese
fat necrosis-follows trauma can sometimes be confused with breast cancer
drug that an vasodilate and decrease relaase of insulin
diazoxide-K+ channel opener, used for emergency HTN and hypoglycemia caused by hyperinsulinism.
endocarditis complicated by staph aureus will likely result in pulmonary abscess and not mitral valve stenosis because
staph aureus will have vegetations on the tricuspid valve which can break of (septic emboli) into pulmonary circulation.
mitral valve stenosis is seen in rheumatic fever group A strep
compensated aortic coarctation.
flow above and below level of coarctation is normal. resistance changes to compensate.
renal failure in the presence of HTN and anemia is caused by ADPKD and not renal cell carcinoma because
ADPKD can cause HTN b/c of renin release and lack of EPO, renal cell carcinoma does not cause HTN
lowers blood viscosity and improves RBC flexibility- used to treat intermittent claudication (cramp in leg due to arterial clot), side effects- dyspnea and mild hypotension
increase in pulse pressure
increase in systolic pressure-arteriolosclerosis. normal is 40 (120-80`)
decrease in diastolic pressure- PDA (blood flows from flows from ductus to pulmonary artery) or aortic regurg (back flow during diastole)
decrease in pulse pressure
mitral valve stenosis, aortic pressure is constant but atrial pressure during diastole increases
infectious dz leading to aortic aneurysm due to destruction of vasa vasorum
pt with abdominal distention and marroon colored stool has what? what is one feared complication?
liver disease which can lead to portal HTN and variceal rupture (rupture of azygous vein-a major out like for esophageal vein which can become engorged from connect to hepatic portal vein)
thiazide causes an increase in ALD and not serum Na+ because
it block NaCl channel in DCT. leading to salt wasting, ALD will increase in an effect to retain salt and can cause a decrease in K/H levels
newborn with transposition of great vessels should be given alprostadil and not idomethacin because
idomethacin would close PDA while alprostadil or misoprotol will keep it open (PGE1 analog)
diastolic decrescendo murrmur on lower left sternal border
veinal drainage of right ovary. left
pampinform plexus-overian vein, IVC
pampinformplexus-overian vein-renal vein-IVC
cervix veinal dramage
cervical vein-uterine vein-external iliac vein
holosystolic apical murrur that radiates to axilla and accompanied by a thrill,
mitral regurg. maya lso have wide splitting of S2 b/c of early closure of aortic valve
systolic ejection murrur, thrill, harsh, and radiates to carotids
diastolic murrmur with love S1 and opening snap below S2
high pitched pansystolic murrmur in 4th intercostal space parasternal region, increased during respiration and reduced in standing position and during valsalva maneuver
Ca2+ blocker, used to control rapid atrial fib and flutter, prefered in pt wirh pulomnary dz b/c not bronchospasm effect of beta-blockers
complication of MI after
-before 5 days
-interventricular septal rupture
-left ventricular free wall rupture
